Enum AbsoluteLength 

pub enum AbsoluteLength {
    Pixels(Pixels),
    Rems(Rems),
}

Represents an absolute length in pixels or rems.

AbsoluteLength can be either a fixed number of pixels, which is an absolute measurement not affected by the current font size, or a number of rems, which is relative to the font size of the root element. It is used for specifying dimensions that are either independent of or related to the typographic scale.

Variants

Pixels(Pixels)

A length in pixels.

Rems(Rems)

A length in rems.

Implementations

impl AbsoluteLength

pub fn is_zero(&self) -> bool

Checks if the absolute length is zero.

impl AbsoluteLength

pub fn to_pixels(self, rem_size: Pixels) -> Pixels

Converts an AbsoluteLength to Pixels based on a given rem_size.

Arguments

• rem_size - The size of one rem in pixels.

Returns

Returns the AbsoluteLength as Pixels.

Examples

let length_in_pixels = AbsoluteLength::Pixels(Pixels::from(42.0));
let length_in_rems = AbsoluteLength::Rems(Rems(2.0));
let rem_size = Pixels::from(16.0);

assert_eq!(length_in_pixels.to_pixels(rem_size), Pixels::from(42.0));
assert_eq!(length_in_rems.to_pixels(rem_size), Pixels::from(32.0));

pub fn to_rems(self, rem_size: Pixels) -> Rems

Converts an AbsoluteLength to Rems based on a given rem_size.

Arguments

• rem_size - The size of one rem in pixels.

Returns

Returns the AbsoluteLength as Pixels.

Trait Implementations

impl Clone for AbsoluteLength

fn clone(&self) -> AbsoluteLength

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for AbsoluteLength

impl Debug for AbsoluteLength

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for AbsoluteLength

fn default() -> AbsoluteLength

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AbsoluteLength

fn deserialize<D>( deserializer: D, ) -> Result<AbsoluteLength, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for AbsoluteLength

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<AbsoluteLength> for DefiniteLength

fn from(length: AbsoluteLength) -> DefiniteLength

Converts to this type from the input type.

impl From<Pixels> for AbsoluteLength

fn from(pixels: Pixels) -> AbsoluteLength

Converts to this type from the input type.

impl From<Rems> for AbsoluteLength

fn from(rems: Rems) -> AbsoluteLength

Converts to this type from the input type.

impl IsZero for AbsoluteLength

fn is_zero(&self) -> bool

Determines if the value is zero.

impl JsonSchema for AbsoluteLength

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn json_schema(_generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

impl Neg for AbsoluteLength

type Output = AbsoluteLength

The resulting type after applying the - operator.

fn neg(self) -> AbsoluteLength

Performs the unary - operation.

impl PartialEq for AbsoluteLength

fn eq(&self, other: &AbsoluteLength) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for AbsoluteLength

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for AbsoluteLength

impl TryFrom<&str> for AbsoluteLength

type Error = Error

The type returned in the event of a conversion error.

fn try_from( value: &str, ) -> Result<AbsoluteLength, <AbsoluteLength as TryFrom<&str>>::Error>

Performs the conversion.
